# Rectangle vs square

One side of the rectangle is 1 cm shorter than the side of the square, the second side is 3 cm longer than the side of the square. Square and rectangle have the same content. Calculate the length of the sides of a square and a rectangle.

Result

a =  0.5 cm
b =  4.5 cm
c =  1.5 cm

#### Solution:

(c-1)*(c+3)=c*c
a=c-1
b=c+3

2c = 3
a-c = -1
b-c = 3

a = 12 = 0.5
b = 92 = 4.5
c = 32 = 1.5
